Epistemic values and the value of learning

In addition to purely practical values, there are cognitive values which figure in scientific deliberations. One way of introducing cognitive values is to consider the cognitive value that accrues to the act of accepting a hypothesis. Although such values may have a role to play in the matter of theory acceptance, this does not exhaust their significance in scientific decision-making. This paper makes a plea for the consideration of epistemic value??cognitive value that attaches to a state of belief. I defend the notion of cognitive epistemic value against criticisms that have been raised against it. A stability requirement for epistemic value-functions is argued for on the basis of considerations of diachronic coherence. This requirement is sufficient for proving the Value of Learning Theorem, which says that the expected utility of cost-free learning cannot be negative. Under the assumption of stability, the expected cognitive epistemic value of undergoing a learning experience must also be non-negative.     

On some early objections to Bohm's theory

Recent literature on Bohm's alternative to mainstream quantum mechanics may create the misleading impression that, except for perfunctory dismissals, the theory was ignored by the physics community in the years immediately following its proposal. As a matter of fact, Einstein, Pauli, and Heisenberg all published criticisms of Bohm's theory, explaining their reasons for not accepting the theory. These criticisms will be discussed and evaluated in this article.     

Sketches of Sikhs in the 1880s

Between 1883 and 1885 the United Kingdoms of Sweden and Norway commissioned a sailing expedition around the world with the frigate Vanadis. On board was the Swedish archaeologist and ethnographer Hjalmar Stolpe who during land excursions collected no less than 7500 cultural specimens for an intended ethnographical museum in Sweden. When reaching India in late 1884 he travelled through the northern British territories, including Punjab, for almost three months. This article gives an overview of the Indian and Sikh ethnographical objects preserved in the Vanadis collection and how the material entered the collection through Stolpe's travels, scholarly networks, and encounters with Sikhs in Punjab.
